Hello again, I am looking to build something similar to the video below. Although after searching for awhile on where to buy good diffraction gratings, my only results pointed to Dragon Lasers. But they are not exactly what I'm looking for, and they don't use Paypal so I'm lost. Anyways any help and/or links would be great! Thanks guys!

How big of grating are you looking for ?

I have them in sizes from 1 x 1 inch up to 10 x 10 inches

I am looking for at least 2" by 2" I found some sheets but they are only 2 axis and I need both for the project. Are you selling them Flaminpyro? If so do you ship to Brazil. Thanks!
